on adding load on a dc shunt motor, the amount of current and torque will increase. but terminal voltage will decrease
The slip rings are the most important brush in DC machine.
swinburne's test on dc shunt machine is to predetermine the efficiency of the dc machine , but it is not accurate it is just like estimation of efficiency of dc shunt machine when it is run as a motor and a generator............................
05 types of dc machines
As we know that skin effect occures in ac system.skin effect dependes on frequncy.In case of dc syastem frequncy is zero.So skin effect for conductor is not applicable for dc.

What motor is NOT suitable for use as a DC machine?

it is a machine which operates on the dc power source.

equation of ac machine
A DC generator is a DC machine that is driven by an external rotating force. It is constructed the same as a DC motor.
PMBLDC machine is actually an ac machine and due to power electronics components it's output is dc ,so therefor it is called 'dc'
ac hall effect always rises and dc is always in steady state.................
Yes, it is normal for a welding machine to convert AC voltage to a DC voltage.
